# Add tags to a new stream when creating a table
<a name="Tagging.Operations.new.table.stream"></a>

You can add tags to streams when you create a new table with a stream using CQL or the AWS CLI to tag a stream.

**Note**  
Amazon Keyspaces CDC requires the presence of a service-linked role (`AWSServiceRoleForAmazonKeyspacesCDC`) that publishes metric data from Amazon Keyspaces CDC streams into the `"cloudwatch:namespace": "AWS/Cassandra"` in your CloudWatch account on your behalf. This role is created automatically for you. For more information, see [Using roles for Amazon Keyspaces CDC streams](using-service-linked-roles-CDC-streams.md).

#### [ Cassandra Query Language (CQL) ]

**Add tags to a stream when creating a new table using CQL**

1. To create a new table with a stream and apply the table tags automatically to the stream, you can use the `'propagate_tags': 'TABLE'` flag. The following statement is an example of this.

   ```
   CREATE TABLE mytable (pk int, ck text, PRIMARY KEY(pk))
   WITH TAGS={'key1':'val1', 'key2':'val2'}
   AND cdc = TRUE
   AND CUSTOM_PROPERTIES={
       'cdc_specification': {
           'view_type': 'NEW_IMAGE',
           'propagate_tags': 'TABLE'
       }
   };
   ```

1. To apply new tags to the stream, you can use the following example.

   ```
   CREATE TABLE mytable (pk int, ck text, PRIMARY KEY(pk))
   WITH TAGS={'key1':'val1', 'key2':'val2'}
   AND cdc = TRUE
   AND CUSTOM_PROPERTIES={
       'cdc_specification': {
           'view_type': 'NEW_IMAGE',
           'tags': { 'key': 'string', 'value': 'string' },
       }
   };
   ```

#### [ CLI ]

**Add tags to a stream when creating a new table using the AWS CLI**

1. To create a table with a stream and apply the table tags automatically to the stream, you can use the `propagateTags=Table` flag. The following code is an example of this.

   ```
   aws keyspaces create-table \
   --keyspace-name 'my_keyspace' \
   --table-name 'my_table' \
   --schema-definition 'allColumns=[{name=pk,type=int},{name=ck,type=text}],clusteringKeys=[{name=ck,orderBy=ASC}],partitionKeys=[{name=pk}]' \
   --tags key=tag_key,value=tag_value
   --cdc-specification propagateTags=TABLE,status=ENABLED,viewType=NEW_IMAGE
   ```

1. To apply different tags to the stream, you can use the following example.

   ```
   aws keyspaces create-table \
   --keyspace-name 'my_keyspace' \
   --table-name 'my_table' \
   --schema-definition 'allColumns=[{name=pk,type=int},{name=ck,type=text}],clusteringKeys=[{name=ck,orderBy=ASC}],partitionKeys=[{name=pk}]' \
   --tags key=tag_key,value=tag_value 
   --cdc-specification 'status=ENABLED,viewType=NEW_IMAGE,tags=[{key=tag_key, value=tag_value}]'
   ```
